✶✶Chapter One✶✶

It was a colorful day of autumn in Ponyville, one that most would say was one of the liveliest. Everything that was expected to go right with the weather went right this year, leaving behind a vibrant palette of leaves that painted the many trees with lovely browns and oranges and reds. The town had blossomed into scenic painting of fall, an artistic inspiration to many.

For Rarity, the season was a fondly remembered time of the year. She found the autumn colors inspired the most out of her creative projects. The vibrant atmosphere sparked so many ideas and so many designs she eagerly waited to make. In a way she tried to capture the brilliant hues of the season in the dresses and clothes she made, hoping to do such rich colors justice.

And with the inspiring season, came a whole mess of ideas. Hundreds of projects and designs popped in the creative unicorn’s head and she was eager enough to try some of them out. This, of course, required more supplies and fabrics to work into her various suits and skirts and hats. She was prompt into ordering plenty of material to work with, but little did she know, she’d overorder in her haste.

This became apparent when she finally came down to the ground floor of the Carousel Boutique one day and was greeted with a room filled to the brim with boxes and crates. Supplies for crafting and outfits for shipping, there was hardly any wiggle room in the area, save for a small, thin path that she had carefully cut through the maze. In her creative haste, she had never thought she’d order so much nor that it’d all clash at the same time.

It went without saying that having dozens of large wooden crates filling up the Carousel Boutique made traveling through the showroom difficult. Rarity had done her best to organize and neatly stack the various crates, moving all those heavy boxes took a lot of effort for the dainty unicorn, she even risked messing up her hair pushing one of them off to the side. Such heavy lifting was a job for somepony else.

She had just finished pushing one of the lighter crates against a wall when there was a knock at the door. “Coming! Coming! Just one moment!” The white unicorn called out to her visitor. It took her another five minutes or so to navigate through the maze of boxes that congested her beloved store. Luckily the one waiting at her door was patient.

When she finally did reach the front door, she opened it up gracefully, revealing a tall red stallion waiting on her stoop. He was a muscler earth pony with an unfathomable work ethic that got the job done. Such commitment was all the reassurance Rarity needed to hire the farmboy for the afternoon.

“G’day, Miss Rarity,” Big Macintosh bowed his head politely, “ah heard you needed some heavy crates moved ‘round?”

“Not a moment too soon, Macintosh,” Rarity replied with a relieved sigh, “I have a new shipment of fabrics coming in tomorrow and I haven’t the space for such an order. I need plenty of space to work, you see.”

The big stallion nodded, “jus’ show me what needs liftin’.”

Big Macintosh was eager to please such a pretty lady like Rarity. It was only proper for an able bodied stallion to help out with the heavy lifting that the petite mare would never do herself. His upbringing told him that it was just the right thing to do.

“Right then,” Rarity started, tapping her chin as she examined the various crates that filled her boutique. “The ones with labels can go into the basement. Won’t be needing those for a little bit. Ones with no labels can be carried up to my workroom. I’ll try to empty some of the boxes so you have less to worry about.”

The big stallion just nodded and went right to work. The crates were hardly a challenge for the big stallion, mostly consisting of fabrics and folded clothes, at least that’s what Macintosh assumed based on the weight. He took to the honest hard work with stride, carrying the cargo wherever Miss Rarity needed it.

Rarity scurried off to her workroom on the second floor, occasionally popping down to grab a few small items out of the various crates. She had been struck with autumnal inspiration and she had to act on it before it was lost. Usually she extracted nothing more than a roll of fabric or a dress in need of tailoring, but Macintosh politely waited for the mare to grab whatever she needed before he carried the box off to its destination. His toughest task was carrying the boxes down to the Boutique basement which connected to the ground floor via a curved, sort of steep stone staircase.

The basement of the Boutique was nothing quite like the glamorous and fashionable showroom that dominated the ground floor. It certainly had a womanly touch, but the ample supply of boxes and storage bins made the place look rather crowded. Already dozens of boxes sat in neatly organized stacks, each one meticulously documented by Rarity. The outsides of all the crates were unmarked, save for some vague shipping information taped to their sides as well as some obscure numbers and abbreviations Rarity likely used as shorthand for her records.

It wasn’t Macintosh’s place to pry, but if he were to guess the boxes most likely contained bulk orders that Rarity had made ahead of time in preparation of a big event. That, along with excess fabrics that she didn’t need right at that moment and extra sewing supplies were likely what filled up all these boxes. And that was enough to settle most of the big stallion’s natural curiosity. At least for that moment.

By the tenth crate carried down into the basement, Big Mac was starting to slow down. Carefully guiding the boxes down the steps while also pausing to allow Rarity to pull whatever she needed out of the crate was taxing for the big stallion and before long he had grown rather tired. But he certainly wasn’t going to take a break now, not when there was more than enough work yet to be done.

Undeterred by a momentary sweat, Macintosh quickly returned to the basement with yet another crate. And then another. A task that was shakily handled by the fatigued stallion. After this crate, he promised himself, he’d take a break.

However, he underestimated himself and quickly found that he bit off a little more than he could chew. Before he knew it, the box was slipping off his back and falling to the ground just as he was stepping off the final steps on the staircase. The box tumbled a bit, noisily scratching against the hard floor. The lid, only loosely held there by small nails popped open in the fall, causing the box’s contents to pour out. There was nothing that could staved Macintosh’s curiosity now.

The contents of the box, oddly enough, consisted of baby clothes, all neatly folded in stacks. At least, they initially looked like baby clothes. The outfits were definitely stylized to match an infantile esthetic, but what Macintosh found strange was that they came in sizes big enough to fit even his large body size. The clothes varied from onesies and cute little sailor suits to printed sun dresses and frilly princess gowns. A well stocked inventory of oversized baby clothes.

Macintosh was puzzled by this discovery. His job fell to the wayside as he picked up one of the outfits off the ground. It was a pink onesie, frilly around the backside as well as the sleeves. It looked like something Applebloom would have been dressed in when she was a foal, but much like everything else, was big enough to fit him. And that simultaneously perplexed him and perked his curiosity.

He could remember the days when Applebloom was just a foal. Granny Smith and Applejack were always dressing her up in these frilly things. He could distinctly remember seeing his baby sister toddling around in pink dresses and things with so many frills on them. And she was too young to really put up much of a fuss. As she got older though, she started to get crabby if they even considered putting her in the girly outfits. He smirked at the silly memories.

Suddenly the onesie he held began to glow a light blue, breaking Macintosh’s concentration. It floated out of his hooves and folded itself back into a neat little square.

“Please do be careful, Macintosh,” Rarity was heard plainly stating, appearing behind the stallion with her horn glowing. She lifted the various onesies, overalls, and panties and folded them all back into the crate. The box’s lid was then closed back up before she continued, “I don’t want any of my inventory ripped or scuffed.”

Big Macintosh was quick to nod, shaking his daydreaming thoughts out of his head. “Won’t happen again, Miss Rarity,” he answered, bowing his head apologetically.

“You’ve been working very hard so far,” “why don’t you take a break and I’ll get you some cold cider to cool you down.”

“‘Preciate it, Miss Rarity!” Maicntosh answered, placing the scuffed up crate down next to the rest of them, wiping a bit of sweat off his brow.

A tiny breather and the cold cider was just the break Macintosh needed. Rarity even offered some fancy luxury tea biscuits as a snack and he was just too polite to say no. The dry biscuits certainly didn’t go well with cider, but their sugary and delicate texture was a tiny adventure for the farmhand’s senses. He almost never ate such intricately flavored things, tasting some exotic spices he never even knew existed.

After only that little pause, he was reinvigorated and ready to get the rest of the crates moved. There was quite a bit of work to be done after all. By early afternoon, he had gotten most of the boxes moved. Some crates were carried into storage while others were carried into Rarity’s workshop where she was sure to thank the stallion for all his hard work. Quickly and efficiently he had emptied the ground floor of the Boutique and was down to his last couple boxes.

He carried one of the crates down to the basement, ready to stack it with the rest of it’s friends with the same colored sticker. He gently plopped it to the ground, taking this time to wipe some sweat off his brow. In that time he noted that it had the same shipping information as the one he dropped earlier. It lacked any other markings save for a label that read “Sound Cirrus Company, Ponyville Distribution Center”.

And that just perked Macintosh’s curiosity even more. He had never heard of such a company, but it didn’t really sound like someplace that Rarity would get supplies from. Perhaps it was a shipping company that dealt in large dress orders. Maybe it was just a fancy name for a fabric distributor. After spending the better half of the morning moving all these obscure boxes from place to place, his curiosity had been mounting.

Without Rarity there to interfere, Big Macintosh’s desire to investigate got the better of him and he pressed on with his little exploration. He loosened the nails of the wooden crate and opened it’s heavy wooden lid to peek inside.

The contents of the container caught the stallion completely off guard. Stacked neatly inside were numerous diapers, all organized into stacks of similar designs. They all came in packs of twenty or so, neatly wrapped in clear plastic. Much like the baby clothes from before, these diapers were big enough to fit adult ponies.

On the very top of the diaper stacks sat a few loose diapers, likely demonstration stock so that customers knew what they were getting. Macintosh picked one of them up for closer inspection.

The diaper was thick, that was certain, and likely very absorbent. Despite its adult size, the garment had a childish print of little hearts dotting its white surface. At a glance, it would almost pass off as a real baby diaper.

Suddenly the wooden lid snapped shut making Macintosh jump with a gasp. The nails glowed blue and magically burrowed themselves into the wood, sealing the box’s contents once again. He took a startled step back, dropping the diaper to the floor as his feet scrambled.

“Couldn’t keep your eyes off my private property, I see,” Rarity glared from across the room.

“S-sorry, Miss Rarity,” Macintosh stammered out, “Ah didn’ mean to intrude.”

Rarity’s horn glowed again as she snatched the heart printed diaper off the ground. “Well intrude you did,” Rarity tapped a hoof as she whipped off some dust that had clung to the diaper, “might get you into trouble poking around at other ponies’ private business.”

Macintosh felt it was only right to apologize. “Really sorry ‘bout that, Miss Rarity. Ah really am-”

“You should know better,” Rarity snapped back, almost acquiring a bit of a motherly tone to her voice, “only a child would disrespect another pony’s privacy like that.” she tapped her hoof some more, “...a child in need of serious discipline if he’s ever going to learn.”

Big Macintosh quietly gulped. An uneasy chill running down his spine. Did she say ‘discipline’?

✶✶Chapter Two✶✶

The two ponies stood there, staring at each other with silent expressions. Rarity had a stern look in her eyes, a unique mixture of disappointment and frustration. Her privacy had been invaded and by her friend’s older brother no less. There was a hint of pondering in there as well, as plans and ideas were passively dwelled upon, but that went completely amiss by Big Macintosh.

Macintosh, on the other hand, was stunned and sort of fearful. The shame of going against his polite upbringing and intruding on Miss Rarity’s private business was enough to cause a bit of color to drain from the big stallion’s face. He never thought he’d stoop so low. Occasionally his mouth would quiver open as he tried his best to formulate a proper apology. He hardly wanted to offend the nice unicorn by overstepping his boundaries.

Every so often Macintosh would feel his eyes wander downward to look at the diaper. It seemed like all this trouble started with that single padded rectangle. The neatly folded pink thing looked so innocent in Rarity’s hooves, hardly something he’d think would lead to such a confrontation. He must have been staring at it for quite some time because by the time he looked back up at Rarity, her stern expression turned into a conniving smirk.

"I trust you've seen a diaper before?" Rarity asked, holding up the diaper, wiggling it in the air for emphasis.

"A-ah have...just..." Big Macintosh struggled to find a steady rhythm in his words, "just never ones so...big before..."

"And I'm sure you know how to put one of these on."

"P-pardon?"

The diaper floated over to Macintosh, mere inches from his face. It was so close he could smell the subtle scent of baby powder laced into the fabric. "Put it on,” Rarity commanded.

“Wh-what?!”

“Put it on,” Rarity snapped again, ”I won't ask again."

With submissive hooves, Macintosh grabbed the diaper out of the air and began to open it up. He glanced back up at Rarity who scowled back at him. It was clear that she wasn’t moving anytime soon. She merely took a step back and crossed her hooves, ready to watch the show.

Macintosh fumbled with the diaper the moment he opened it up. His hooves wouldn’t stop shaking as the pressure of doing a good job for Miss Rarity kept him tense. But how hard could it be? He had changed hundreds of diapers when Applejack and Applebloom were little. This couldn't be so different. His diaper changing knowledge was a bit faded, but surely going through the motions would spark some sort of muscle memory.

When he threaded the diaper up between his back legs, he found that his memory wasn’t quite as fresh as he initially thought. His diaper changing skills, as he quickly discovered, only extended to changing others. Putting one on himself proved to be a difficult thing to pull off. Suddenly his perspective on things were off and he struggled with the tricky task.

After a longer than average time, Macintosh managed to thread his tail into the back and tape the whole thing together using the provided diaper tapes. The fit was very clearly loose and the tape job was crooked, but in his eyes the solution was passable. He looked up to Rarity for some sort of approval. He had the diaper on, surely that’d be enough.

Rarity just rolled her eyes as her horn began to glow, "Oh come now. It's just a diaper." In one fluid motion, Macintosh's diaper shifted around his waist and readjusted itself. Loose tapes were undone and quickly replaced in their rightful place, giving the garment a snug and secure fit. Macintosh gasped and felt his body tense up as he felt the pillowy soft material shift around his backside, sealing his lower half in with hardly any gaps for the open air to breeze through.

“There,” Rarity stated plainly, “that’s how a diaper’s supposed to fit around a pony. After a display like that, I'll be personally handling all your diaper changes from now on."

"Wh-what?!"

“One less thing to worry your little head about,” Rarity replied, topping the comment off with a condescending pat on the head, “now that I have you diapered, we can get some use out of you. Follow me up to the showroom.” She beckoned the stallion towards the steps leading back upstairs, walking with her usual amount of grace. “And be a dear and grab that crate you dropped early while you’re at it. I have a feeling we’ll be needing some new clothes.” She then paused, turning her neck backwards, “and you know better not to take that diaper off, right? Because that’d be awfully naughty if you did.”

Big Macintosh gulped and compliantly nodded. “Y-yes, Miss Rarity.” He probably nodded a few too many times then necessary, but the blushing stallion could hardly keep track.

Satisfied with the answer, Rarity turned herself around and walked out of the basement. Her curled and fashionably styled tail swished side to side as she left, as if it was beckoning Macintosh to follow.

Left alone, Big Macintosh stood there frozen as his blushing ears listened to dainty footsteps that slowly faded away. He took a moment to process it all, his thighs occasionally squeezing together as if to subconsciously remind himself that he was, in fact, wearing a diaper. A fleeting thought reminded him that wearing a diaper wasn’t exactly a prison sentence. He could easily take it off and run away before Miss Rarity was any wiser. But that would be naughty, another thought parroted the mare’s words. It might have been the diapers doing some strange things to his mind, but he was inclined to listen to this second thought. He rationalized that he couldn’t leave until he figured out what Rarity had planned. Because instead of scolding him or throwing him out of her place, she was asking him to take some clothes upstairs. Once again he found himself a slave to his innate curiosity.

The baby clothes box was easy enough to find among the rows of high stacked boxes. It had visible scuff marks streaking across one side, separating it from the dozen other crates piled beside it. When he lifted the box onto his back, he found the bulk of his diaper threw him off a bit, interfering with the natural motions of carrying heavy objects that he grew so use to. It seemed like the diaper jumped at every opportunity to impede his movements and remind him that it was there. Staggering a tiny bit, he carried the box back upstairs where Rarity was waiting for him by the display stage.

Off to the side of the Carousel Boutique stood this round, raised platform that was the mare’s goto location for fitting dresses and showing off new outfits to clients. It’s half circle wall of tall mirrors provided various directions for a pony to examine the look of an outfit to ensure that they looked good at all angles. Any sewing supplies were in easy reach from the stage, providing Rarity a handy workstation.

The mare was already gathering a mess of sewing supplies close to the stage in preparation of what was to come. When Macintosh neared the stage, she only gave him a passing glance out of the corner of her eye. “Lovely,” she stated as he placed the crate of clothes next to the stage, “now waddle up on stage, baby boy.”

Macintosh blushed and hesitated for only a second before he hopped up onto the stage without a word. He thought to correct Miss Rarity by saying he was much older than a baby, but the very idea of making such a correction felt silly. The only sound that came from the stallion was the loud crinkling of his diaper. The sound made his ears sting with red hot embarrassment.

“I’ve had so much stockpiled for my more private clients and no way to try out new ideas. Can you believe that?” Rarity mused as she cracked open the crate, taking the lid completely off. “I think we can make the best out of your snooping.” She grinned up at the diapered stallion before focusing her magic on the open box.

In a flurry of color, the stacks of clothes and fabrics came blooming out of the box like a fountain. Neatly folded onesies and t-shirts, shortalls and dresses floated upwards into the air before cascading around the two ponies until settling in a slowly rotating ring. From this set up, Rarity handpicked items that stood out to her artistic eye.

Macintosh’s embarrassing situation fell to the wayside as she focused her attention on the swirling string of giant baby clothes. She picked out a number of outfits from the selection. Onesie and bonnet combos, shortalls and matching undershirts, even a couple dresses and frilly panties much to Macintosh’s embarrassment. Every set was kept together in a floating stack, expertly organized by the fashionable unicorn.

Meanwhile Big Mac was forced to wait it all out. He watched in increasing embarrassment as the mass of outfits rotated around the stage, gliding right past his field of view. Footed sleepers, soft stretchy pants, even sets of brightly colored kid shoes. The level of detail put into these near perfect, enlarged reproductions was staggering. The infantile implications very nearly put Macintosh’s diaper to shame. Who knew Rarity was so well prepared for such an occasion.

After no time at all, Rarity had her first wave of outfits she wanted to try out. Each one was so neatly placed along the edge of the stage, alluding to what was to come. First a delightfully infantile onesie set was pulled over Big Mac’s body. A light blue onesie brightened his red coat as a white and blue baby bonnet was simultaneously tied over his head. For added flare, Rarity even popped a green pacifier into his mouth.

“A casual little number for quiet days around the house,” Rarity added, tapping her chin and making some quick adjustments around the hem lines, “And I’m happy to see the onesie fits well over a bulky diaper. We always want a snug fit around those, don’t we, baby?”

Macintosh’s eyes darted to the floor as he blushed. He was only able to suck on the pacifier for a few moments before the outfit was gently pulled away from his person. Everything was pulled off save for the pacifier and diaper, leaving him in that uneasy state of exposed as he was before.

Next up was a pair of coveralls and matching undershirt. A more ‘outdoor playtime’ outfit according to Rarity. The dark blue jean material had a natural resistance to scuffs or grass stains and the undershirt kept the wearer decently covered up.

“Hmm, it looks good,” Rarity mused to herself before tugging on the pant legs with her magic, “but perhaps a few snaps around the inseam will help make diaper changes a little easier...”

Rarity had Macintosh model at least ten other outfits after that, each one with their own little tweaks to be made. The mare would often think out loud, spouting out prodding questions or mental notes for how to improve the clothing for her clientele. All of this information was unnecessary to Macintosh of course, forcing him to remain quiet throughout the entire ordeal. It seemed like Rarity would make it a game to come up with questions about Macintosh’s current outfit that would make him blush or squirm or even let out a subtle whimper.

She wouldn’t allow him to forget about the diaper, which she seemed to enjoy seeing on him more than anything. She’d often give it a quick diaper check to ensure that he was still dry, sometimes even reminding him to ask her if he ever needs to go potty. Most of the outfits put on Big Mac was centered around the diaper, usually designed in such a way that diaper changes wouldn’t be too difficult with them on.

“And last but not least!” Rarity announced at the end of it all, levitating a pink and purple mass to the diapered stallion, “something pretty for the big, tough stallion!”

Macintosh gulped as he looked over the outfit. It was the outfit that he was dreading the most. It was a frilly pink sundress made of a light, flowing material, designed to keep the wearer cool even during a whole afternoon of running around in the park. A built in onesie kept the diaper snug and close to the wearer’s rump, providing an added bit of security. The set even came with a set of ribbon laced bootie that came with pads at the base for added comfort. A girly nightmare of a costume.

Despite the stallion’s obvious reservations of the clothing Rarity proceeded as usual. Like the many outfits before, she took it upon herself to dress him up, guiding his legs through the layers and making sure everything was straight and in place. In a last minute decision, she even tied a few big bows in Macintosh’s mane, adding to the already girlish appearance.

“Well I would never have thought you’d look so cute in a dress,” Rarity praised, “I’ll have to see to making some more pretty dresses for you in the future.” She smiled at the sight for a moment before an idle thought pulled her attention away. She scanned her little workstation and concluded that there was one thing that was missing. Maybe even two. “Oh but I’ll be needing my notepad,” she simply said, “stay right there. I’ll only be a moment.”

Macintosh quietly nodded, shifting a tiny bit on his hooves to find a slightly more comfortable pose to stand in. Moving just made the dress rustle even more as if the bright thing needed to remind him of its presence. Anytime he accidentally glanced up from the ground, he would catch a glimpse of himself in the mirrors, clad in that girly dress with its obvious diaper bulge.

A growing pressure developed in his lower belly. A kind of pressure he had hoped wouldn’t come. Unbeknownst to him, while he was standing as Rarity’s diapered clothes model, the exotic spices in the cookies he ate mixed with the cider and an unprepared digestive system began to conjure up a churn in his gut that foreshadowed an inevitable consequence. It was only now that this churning became big enough to be noticed by the diapered stallion and he could feel his blood turning cold as the gravity of the situation dawned on him.

Panic started to settle in as the need to use the bathroom grew. He started to look around the room for some sort of escape route, whether it was a hidden bathroom he could relieve himself in or some hole he could forever hide in. His darting eyes eventually settled on the boutiques front door. Such a favorable escape route an hour ago, but now it was an unthinkable alternative to the dress wearing stallion. A tiny voice in his head also concluded that doing something so drastic and brash would be rude to Miss Rarity. And there was no telling what she might end up doing if she found her new diaper model went missing. A single squirm and a surrendering whimper was all that was heard from the stallion as he settled back down on top the round stage and forced himself to patiently wait for Rarity’s return.

His body seemed to understand the situation better than he could because the moment he settled back down he was attacked by an overwhelming urge to squat. A groan slipped right past his pacifier as a dreaded chill ran down his spine. His diaper quickly began to expand out the back, filling up with a sizable mess that his bowels were all to happy to push out. The dress’s hidden away onesie strained as the diaper underneath bulged and sagged with the added weight. The plastic snaps kept most of the expanding at bay, causing Big Mac’s shameful fill up to squish itself up to the front of his diaper.

Despite feeling the sticky muck teasing the very back of his balls, Macintosh had no choice, but to finish the dirty deed. He was frozen there for a few long, agonizing minutes, hunched over and pushing at his gut as best as he could. Tiny huffs and grunts slipped passed his pacifier as he gripped it’s rubber nipple between his teeth.

Finally the dirty deed was done, leaving Macintosh with a unique mixture of relief and undeniable shame. From his position on stage, there wasn’t a single mirror that could see past his dress, which in a way he was thankful for. He couldn’t bear to see the mess he had made.

“I’m back, diaper boy!” Rarity’s voice was suddenly heard, making Macintosh shrink and take in a shocked breath of air. “And what could possibly be the matter now?” Rarity asked, quirking an eyebrow. But seconds after asking, the smell hit her. Shocked at first, her expression quickly devolved into a devilish grin.

Big Mac shrunk back as his body instinctively scrunched up. He turned to face Rarity with his ears tucked back and his face flaring up a bright red. In a shameful panic he thought facing her would at least cover up the diaper, but that only allowed the mirrors behind him to give her plenty of angles to inspect the saggy thing.

“Oooh we’re quite the little filly, aren’t we...” Rarity’s grin grew. With a magical flick of her horn, she unsnapped Macintosh’s onesie, revealing the messy diaper underneath. The garment had a noticeable lumpiness to it, a distinctive, infantile look. “What a messy! Little! Filly!” Rarity cooed excitedly as she gave him a couple condescending tickles under his chin, “couldn’t hold it in for just a little longer? Couldn’t ask Miss Rarity to use the potty?”

“I-It wasn’t...I-it was an accident...” Macintosh stammered out in something that sounded like a childish grumble. The humiliation of standing before Miss Rarity in a used diaper made his words fail him. His face burned with an intense embarrassment that was so strong he could hardly look Rarity in the eye.

“A pretty big accident,” Rarity answered, “something I’d never expect from a big tough stallion.” She chuckled to herself, shaking her head, “oh but what am I saying. I’m dealing with a nosey little child.” Her horn glowed once again, lifting a padded out from behind her back. “A nosey little child just begging to be punished.”

Macintosh gulped with wide open eyes as the wooden paddle came into view. The paddle was long and flat with black diamonds painted on its surface. The handle was bound with a blue silk that was all decorative considering that Rarity would likely never hold the thing in her hooves.

Rarity made sure that Macintosh got a good look at the paddle. “You know, it’s funny,” she started, tapping the paddle’s flat face against her hoof, “here I am diapering you and dressing you up like a little pretty filly...And I don’t hear a single complaint from you.” She circled the stallion a few times, twirling the spanking paddle around like a baton. “Just think, if you REALLY didn’t like what I was doing, you could have easily ripped off the clothes and run out the door.” Suddenly she stopped her circling, right behind the stallion’s diapered behind. The wafting stench of the thing tickled her nose as she mused. “But you know that’d be very naughty,” she grinned, lining up a shot with the paddle, “you might ruin Mistress Rarity’s pretty clothes.”

With a swipe of her horn, the paddle reared up and came crashing down onto Big Mac’s diaper, producing a muffled and moist thump. The diaper absorbed some of the impact, but the paddle came down with such force that Macintosh was sure to feel the squishy mess inside shift about, adding more shame to his already infantile display. That spank was followed by another swung just as hard and then another and another.

Rarity took a moment to catch her breath, pulling her head back and fixing some stray hairs that shook loose. “So instead of ripping off the clothes and running off, you soil yourself and wallow about in your dirty diaper like a little foal,” she scolded as she continued her circling, “...as it should be.” She stopped right in front of Macintosh’s lowered head, locking eyes with the humiliated stallion. “You have made Mistress Rarity very very happy,” she grinned, patting Macintosh’s head, “very happy.”

In the midst of all this teasing and punishing, something began to stir in the dark recesses of Big Mac’s mind. Despite everything, he actually felt a swell of pride stirring from the praise Rarity was giving him. All the extra attention she was giving him gave him a strange sense of happiness, a stark contrast to the deep burning humiliation he had felt up until now. And in an even stranger sense, he even felt himself feel a little intrigued by it all. To be put in his place by such a dainty unicorn. It was all rather exciting.

“Oh but it wouldn’t be a punishment if we just spanked the little filly’s bottom a little bit and called it quits.” Rarity started again. “No, how about...twenty swats. That should set the snoopy filly straight.“

A simple enchantment was casted onto the paddle as it floated up into the air and back behind the diaper stallion. With a life of its own, the paddle started to swing at Big Mac’s rump by itself, giving the diaper a hearty smack each time. It continued this at a steady pace, whacking the discolored diaper, pausing, and then reeling back for another one. All the while Rarity continued about her business, tidying up the place and getting things all organized.

Macintosh was frozen where he stood, not wanting to anger Rarity further by stepping away from the spanking paddle. He just lowered his head to the ground, bracing with his entire body to endure the entire length of the twenty spanks he had in his future.

The smacks were strangely rhythmic, robotically striking with the same force, same timing, and same pace. Each spank drove the messy muck farther through his diaper, spreading it out. His body would lurge a tiny bit forward each time the paddle made contact, shaking his system a minute amount.

Rarity continued to do odd jobs around the store as Macintosh was subjected to her punishment. Occasionally she would glanced up at the diaper stallion, shooting him a naughty smile before returning to her job. She reveled in the power trip she got from punishing the diapered stallion, even when she wasn’t actively doing anything to him. To pay so little attention to Big Mac made it more savory to the white unicorn.

Soon she returned just as the paddle had finished its steady stream of punishment. “I suppose it'd be best we get you changed out of that filthy thing. I have clients coming over soon and I don’t want you stinking up the place.” Macintosh looked up with surprise with almost a twinge of fear in it as his mouth stammered open a tiny bit. His pacifier tumbled out of his mouth. Rarity was quick to pick up on all this. “...Unless you want me to change you in front of my clients when they arrive. Is that what you want?” Big Mac quickly shook his head no, a terror stricken look on his face. “Thought so. Then lay on your back for me. Oh and do be careful. We wouldn’t want you to land on that messy lump of yours.” She was joking of course because the bulk in the back of Macintosh’s diaper had long since flattened against his rump, clinging to his backside like moist clay.

As Rarity pulled out the necessary supplies from the clothing crate, Macintosh steadily lowered himself to the ground. He felt silly laying on his back like that, his dress being pushed every which way before settling down in a ruffled pile. It made his messy diaper feel all the more ridiculous. But he was powerless in the situation. All he could do was stare up at the ceiling and allow Rarity to change him out of the filthy thing.

Rarity started with untaping Macintosh’s diaper. She kept her head craned away from the stink, heavily relying on her magic to get the job done. She avoided using her hooves for almost everything, expertly pulling the diaper out and wiping the stallion’s rump clean with her magic. She focused most of her cleaning job on the brown filth that clung to Big Mac’s butt, but every now and then she’d use a wayward wipe to clean his crotch as well.

Macintosh’s member, remaining mostly limp for the better part of the afternoon, was brought to life by the cold wipes that so delicately brushed against it. Despite the humiliation, the punishments, and shame, his body betrayed him and he found himself growing semi-hard from the wipes.

Rarity didn’t outwardly acknowledge the stallion’s shameful erection, but she was sure to take a mental note of it. To her it confirmed that this wasn’t entirely a punishment for Macintosh. Part of him, even if it was just a small part, was starting to enjoy it.

As the messy diaper was rolled up into a ball, the Boutique’s doorbell rang. “Be right there!” Rarity called out, magically floating the diaper over to Macintosh’s front hooves. “When I’m done changing you, you’ll take this thing out to the dumpster in the back,” Rarity gave him directions as she unfolded the new diaper. “THEN when you’re finished I want you to come right back on stage, alright?”

“Y-yes Miss Rarity,” Macintosh stammered out, taking hold of the rolled up diaper. He held the heavy mass lightly, doing his best to keep it as stretched away from his nose as possible. To think he was actually wallowing around in such a mess not minutes ago.

Rarity rushed through the rest of the diaper change after that. A quick sprinkling of baby powder and the fresh, crinkling diaper was pulled up between Macintosh’s legs, snuggly taped around his waist. Before long Macintosh was back on his feet, his old stinky diaper held in front of him.

“Don’t be too long now,” Rarity added before cleaning up the area and trotting towards the front door.

Macintosh was quick to dart into the backroom with his diaper in hand. The fear of being seen by a stranger was enough motivation to get him out of the showroom as quickly as possible. He peeked out the back door, his eyes scanning the horizon outside for any sort of movement. Not a single soul was seen, only trees and tall grass. He inspected the area thoroughly, double checking and triple checking the place before he even thought about stepping outside.

Sitting a fair distance away from the store was a green metal dumpster. Usually a place for discarded fabrics or expired food, the metal container felt like it was miles away from the door, making Macintosh’s face drain of color. His grip around his old diaper tightened as he mentally prepared himself.

In one mad dash, Macintosh scrambled out the door and across the way, tossing the diaper into the dumpster the moment he got close enough. His dash resembled more of a waddle though, with his diaper crinkling loudly under his dress. He dared not to look up at any point in his run with his eyes locked onto the dumpster and than the backdoor. He moved so fast that he came dangerously close to tripping over his own feet, which would likely lead to getting mud on his pretty new dress. But as luck would have it, he managed to run to and from the dumpster with hardly any difficulty at all.

Once he was safely back inside, he slammed the back door, leaning against it as he gasped for air. He plopped to the ground as he panted, relieved that that dreadful task was done.

“Welcome! Welcome! Do come in!” Rarity was heard at the front door, “I’ve been looking forward to your visit!” Her voice echoed through the quiet Boutique, acting as a painful reminder to Macintosh. No matter what he’d have to go out there and face the music. Diaper, dress and all.
